DraftKings has a sports bet promotion going called "Hammer the Over." If I'm interrupting this bet correctly I can't believe my eyes.

What do you make of this:
The promotional Points Total will reduce by 0.5 pt’s for every 5,000 customers that bet the market. i.e. if the original Points Total is 50 and 100,000 customers place an eligible bet, the promotional Points Total will reduce to 40
- The ‘Hammer the Over Total Special’ will settle as a winner if the Points Total in the game exceeds the final promotional Points Total

I made my bet at 19, right now its down to 7.5. I tried to make a larger bet, but I could only make a $25 bet. Does this mean if the total game score is over 7.5 you win the bet? Anybody else betting on this?
